This product is a fully automatic concrete shrinkage and expansion meter based on intelligent sensing. It is designed for construction engineering, laboratories and scientific research fields, and is committed to providing high-precision and high-efficiency concrete deformation monitoring solutions. The equipment adopts an integrated design and is equipped with a high-sensitivity sensor, which can capture the tiny deformation of concrete during the hardening process in real time, helping users to accurately grasp the trend of concrete performance changes.
Core highlights:
Fully automatic monitoring: No human intervention is required, and data collection, analysis and report generation are automatically completed, greatly improving work efficiency.
High-precision sensing: Using nano-level sensors with an accuracy of up to ±0.001mm to ensure data reliability.
Energy saving and environmental protection: Low power consumption design, in line with the concept of green environmental protection, suitable for long-term monitoring scenarios.
Application scenarios:
Concrete quality monitoring of large infrastructure projects (such as bridges and tunnels)
Laboratory concrete material research
Real-time monitoring of construction sites
Contact shrinkage test requirements in GB/T50082, Standard for Test Methods of Long-term Performance and Durability of Ordinary Concrete
Technical Specifications for the Application of Shrinkage Compensating Concrete JGJ/T178, GB50208, Quality Acceptance Specifications for Underground Waterproofing Projects
Technical Specifications for the Application of Concrete Admixtures GB50119, etc.
1. Smart touch, easy operation: Equipped with a 7-inch color touch screen, it can display and record the shrinkage and expansion values of the specimen and the ambient temperature and humidity in real time, with automatic operation, saving time and effort.
2. Convenient data export: The test data can be directly exported to the computer via a USB flash drive, supporting Excel format, which is convenient for subsequent analysis and processing.
3. Worry-free software upgrade: Built-in dedicated software supports easy upgrades through the USB interface to ensure that the device always maintains the latest functions.
4. Power-off data protection: The unique design ensures that the test data is continuously saved and will not be lost even if the power is accidentally cut off.
5. Flexible function expansion: The host reserves 4 spare interfaces to facilitate users to expand functions according to their needs (value-added services).
6. Multiple models to choose from to meet diverse needs: Three models, type I, type II, and type III, can be used to perform 1, 2 or 3 groups of tests at the same time, and can be flexibly adapted to different experimental scenarios.
7. Customized mold: The measurement mold size can be customized according to the size of the test block, and vertical, horizontal and expansion rate-limited molds are provided to meet diverse experimental needs.
